AMT-700 Inmarsat High Gain Antenna The AMT-700 is typically housed under a tail-mounted radome, but can also be mounted at several locations on the fuselage. The use of an integrated ACU enables greater flexibility during installation and reduces the number of units required. ARINC 781 DLNA interfaces allow this system to be used with any manufacturer's SwiftBroadbandapproved HPA or terminal. The eNfusion® AMT-700 is a complete and has an integrated ACU in order to ARINC 781 High Gain Antenna (HGA). provide greater flexibility for installation. The antenna is used to receive and The antenna’s technology and design transmit voice and data from aircraft via the Inmarsat satellite network, and supports multi-channel SwiftBroadband (Class 6 services). Form Factor The AMT-700 is a mechanically steered Inmarsat antenna that meets ARINC 781 (U.S. patent pending) result in the highest gain of any Inmarsat mechanical high gain antenna – achieving greater than 13.5dBic over 100 percent of the Inmarsat coverage volume.
